The last century’s space race was a competition between the world’s great powers and a test of their ideologies. It would prove to be a synecdoche of the entire Cold War between the capitalist United States and the socialist Soviet Union.
The starting pistol in the race to the future was fired in 1961 when President John F Kennedy committed to “achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the Earth” and it ended with a US victory on 24 July 1969 when the crew of the Apollo 11 mission splashed down safely in the Pacific Ocean.
There are no such stakes in today’s race. The values of the future aren’t in question, merely the egos of three billionaires. One of these men is launching his private spacecraft off the planet on Sunday. Another follows suit soon after.
So here’s how they compare and what you need to know:

Sir Richard Branson
Age: 70
Estimated Net Worth: $5.8bn (£4.2bn)
Company: Virgin Galactic
Launch date: 11 July
“My mum taught me to never give up and to reach for the stars,” said Sir Richard Branson announcing that he was going to be among the first people his spaceflight company launches on a mission.

Unfortunately, not only will Virgin Galactic’s mission fall short of the stars, the two-and-a-half hour mission will also fall short of space, at least according to the internationally agreed definition.

VSS Unity is a spaceplane (perhaps just a plane?) that launches in mid-air from the belly of a carrier aircraft at an altitude of about 15km, and then flies up to an altitude of about 80km, allowing the passengers to feel nearly weightless for approximately six minutes and glimpse the curvature of the Earth.
The problem for Sir Richard is that the Federation Aeronautique Internationale (FAI) defines the boundary between Earth’s atmosphere and outer space as 100km above Earth’s mean sea level, the so-called Karman Line, 20km higher than he is going to travel.

The definition of the edge of space is a bit of a challenge. Earth’s atmosphere doesn’t suddenly end but becomes progressively thinner at greater altitudes. In very simple terms, physicist Theodore von Karman’s solution was to define the edge of space as the highest point at which an aircraft could fly without reaching orbital velocity.
While Karman himself and the FAI regards this altitude as 100km, Sir Richard has the US Air Force and NASA on his side. They both place the boundary of space at 80km above mean sea level, partially because putting it at 100km would complicate issues regarding surveillance aircraft and reconnaissance satellites for the US – although the Department of Defence subscribes to the FAI definition.
It’s not clear whether this definition is covered by the small print of Virgin Galactic’s customer tickets, but ultimately the company aims to be operating multiple space tourism flights a year, and already has more than 600 customers for the $250,000 (£189,000) seats – including Justin Bieber and Leonardo DiCaprio.

Jeffrey Bezos
Age: 67
Estimated Net Worth: $198bn (£144bn)
Company: Blue Origin
Launch date: 20 July
“Ever since I was five years old, I’ve dreamed of traveling to space. On 20 July, I will take that journey with my brother,” said Jeff Bezos, announcing his seat on a journey to the edge of space.
Blue Origin’s New Shepard rocket is capable of actually making it there, with a maximum achieved altitude of above 100km, but how high it will bring its four passengers hasn’t yet been confirmed.
These passengers will be Jeff Bezos, his brother Mark, a mystery customer who paid $28m (£20m) for the seat in an auction, and 82-year-old Mary Wallace “Wally” Funk, a woman who had astronaut training in the 1960s but was denied the chance to go into space because of her gender.
While the mission will be scooped to launch by Virgin Galactic, by inviting Wally Funk it has managed to scoop Branson on getting a famous victim of gender injustice into space – she had previously put money down to fly with Virgin Galactic.

It will take three minutes to take the passengers up to the required altitude, at which point they will have three minutes more in which to enjoy their sudden near-weightlessness. They’ll be allowed to unbuckle their seatbelts and float around, as well as examine the curvature of the Earth through one of the capsule’s windows. Just over 10 minutes after launch, the spacecraft will land back on Earth.
The 20 July flight will fittingly occur on the anniversary of the moon landings in 1969, but unlike the Apollo missions there will be no human piloting the modules. Instead, Blue Origin’s New Shepard spacecraft is completely autonomous and will follow a programmed mission timeline before parachuting back to Earth.
The company has said that it expects to sell seats for more tourism flights in the future, but it isn’t clear how this will happen and the tickets for New Shepard are yet to go on general sale.

Age: 50
Estimated Net Worth: $167bn (£121bn)
Company: SpaceX
Launch date: Unknown
“I want to die on Mars – just not on impact,” Elon Musk once quipped, although he hasn’t announced his immediate intention to travel into space at all.
Unlike both Bezos and Branson, Musk’s private spaceflight company, SpaceX, has a long and successful history of launching payloads way beyond the 100km mark.
SpaceX has announced it will be launching an all-civilian mission into orbit by the end of the year, with the passengers actually orbiting around the planet for up to four days before returning to Earth.
All four crew seats on the mission have been paid for by Jared Isaacman, the founder of Shift4 Payments, who has declined to reveal the costs.
Isaacman is donating two of the seats to St Jude Children’s Research Hospital in Memphis, with one being given to a staff member there, and another intended to be raffled off to a member of the public. He hopes to raise $200m (£145m) for the hospital, alongside a $100m (£72m) donation of his own.
Elon Musk hasn’t mentioned flying on this mission himself, although he has long articulated a plan to travel to Mars, plans that have been described as a dangerous delusion by Britain’s chief astrophysicist Lord Martin Rees.

Back in 2016, Musk outlined his vision of building a colony on Mars “in our lifetimes” – with the first rocket propelling humans to the Red Planet by 2025.
For many years the company used an image of the Martian surface being terraformed (turned Earth-like) in its promotional material. However, a NASA-sponsored study published in 2018 dismissed these plans as impossible with today’s technology.
Recently Musk has tweeted he believed it was “possible to make a self-sustaining city on Mars by 2050, if we start in five years” but as of yet, SpaceX has not planned any missions to the planet.
Hostages have been killed after separatist militants hijacked a train carrying hundreds of passengers in Pakistan, authorities have said.
The Pakistan military (ISPR) said 21 hostages were killed, as well as four security force soldiers, on the train that was carrying more than 400 people.
Earlier on Wednesday, the Baloch Liberation Army (BLA) claimed responsibility for the attack and said they had killed 50 people.
A Pakistani government spokesman described the attack as “an act of terrorism,” and passengers who had been freed described how gunfire was “coming from everywhere”.
ISPR director general Ahmed Sharif Chaudhry added in a statement: “Today we freed a large number of people, including women and children. The final operation was carried out with great care.”

The train was hijacked on Tuesday as it entered a tunnel in Bolan, a district in the southwestern province of Balochistan.
The Jaffar Express was packed with 440 people, including women and children, Mr Chaudhry told local broadcaster Dunya TV.
He added that “militants were in touch with their handlers and masterminds in Afghanistan via satellite phones” during the incident.

The train was on a 1,000-mile journey from Quetta to the city of Peshawar.
Militants blew up the railway tracks before firing at the train, killing the driver and trapping it inside a tunnel at Mashkaf.
Security forces exchanged gunfire with the militants who were wearing vests loaded with explosives.

‘God saved us’
Noor Muhammad, who was travelling with his wife, said: “First, they hit the engine with an RPG (rocket-propelled grenade).
“After that, gunfire started and explosions were heard, RPGs were used. God saved us.
“They made us get off (the train) and told us to get down or they would shoot. We got down and then they said ‘leave’.”

Bashir Yousaf, who was with his family, said: “Everyone was crying and passengers were shouting, everyone was lying on the floor trying to save their lives.
“The sound of gunfire was coming from everywhere, then they (insurgents) told us to get down.
“After getting off we were told not to look back. I just kept walking without looking back to save my family’s lives.”

Mr Chaudhry added to Dunya TV that security forces “first took out some of the militants and then began clearing compartment by compartment killing the militants”.
He said the total number of militants was 33, and added that no passenger was hurt or killed during rescue operations.
However, he added that before “the final clearance,” 21 people were killed by the militants. Four Frontier Corps soldiers were also killed.
“Perpetrators will be hunted down and will be brought to justice,” he said. “This incident of the Jaffar Express changes the rules of the game.”

Earlier in the day, Pakistan’s Prime Minister Shehbaz Sharif condemned the attack and said security officials were “repelling” the militants, while interior minister Mohsin Naqvi called the attackers “enemies” of the country.
The BLA – designated a terrorist organisation by the UK – had demanded the release of Baloch political prisoners, activists, and missing persons within 48 hours.
It had threatened to start executing the hostages if the government did not fulfil its demands.
The group often targets infrastructure and security forces in Balochistan but has also struck in other areas, including the southern port city Karachi and the strategic port of Gwadar on the Arabian Sea.
Hostages have been killed after separatist militants hijacked a train carrying hundreds of passengers in Pakistan, authorities have said.
The Baloch Liberation Army (BLA) claimed responsibility for the attack and said they had killed 50 people on the train that was carrying more than 400.
Government officials have not confirmed how many hostages have been killed. Sarfraz Bugti, the chief minister in Balochistan province, said “we people have also been martyred, but we will share details later”.
More than 50 militants have been killed and the insurgent attack has now ended after a day-long stand-off, according to officials.

Security officials told the Associated Press news agency that more than 300 hostages had been rescued.
Pakistan’s junior interior minister Talal Chaudhry said 70 to 80 attackers had hijacked the train.
A Pakistani government spokesman described the attack as “an act of terrorism”.
Passengers who have been freed described how gunfire was “coming from everywhere”.

Greenland’s centre right opposition party has won the most votes in elections that will be seen as a rejection of Donald Trump’s interference in the island’s politics.
The Demokraatit party won 30% of the vote. It favours a slow move towards independence from Denmark.
On the eve of the election, its leader Jens-Frederik Nielsen had told Sky News voters should use the election to warn the US president not to meddle in their future.
He said: “I hope it sends a clear message to him that we are not for sale.
“We don’t want to be Americans. No, we don’t want to be Danes. We want to be Greenlanders. And we want our own independence in the future. And we want to build our own country by ourselves, not with his hope.”

Donald Trump has been actively trying to prise Greenland away from Denmark, urging its people to determine their own future and join the United States.
A few days before they went to vote he promised “billions of dollars” in investment telling them he will “make you rich”.

Does Greenland want to be part of the US?
The territory’s second opposition party Naleraq made big gains in its share of the vote. It wants a swift move to independence.
One candidate, Qupanak Olsen, told Sky News Donald Trump’s interference had helped its cause.
“It’s making us aware, we are worth more than what the Danish people have been telling us for the last 300 years, maybe we can stand on our own two feet,” she said.
The party’s relative success may give Trump and its supporters hope they can do more to encourage independence in the future.

Why does Trump want Greenland?
But it’s important to stress joining the US is not a popular idea here.
Even Ms Olsen rejected any moves towards joining the US, saying Greenland would not swap 300 years of colonialism under Denmark for more of the same under the US.
There were bigger issues dominating the election for Greenlanders. Insufficient healthcare, especially for cancer treatment for instance, is a major grievance on this remote but vast island.
But for the US president this was all about his neo-imperialist ambitions, openly musing yesterday about erasing borders between the US, Canada and Greenland.

His brazen play for Greenland and its vast largely untapped mineral wealth did not go down well among the fiercely independent islanders.
President Trump’s unashamed meddling has baffled observers. He says Greenland is vital for America’s security, and yet the US already has military bases on its territory and has been offered the possibility of building more.
Equally, US mining companies have every right to join the effort to extract its huge mineral wealth, as Chinese, European, Canadian and Australian firms have been attempting for decades.
It is however not an easy process. Greenland’s vast size, lack of roads and Arctic climate are huge challenges.
It is as reluctant to yield its mineral riches as it seems its people are to succumb to the advances of a US president.
This election shows Donald Trump will have to try harder if he wants to win the affections of Greenland’s people and Greenland’s elusive natural bounty.
